Eternity Designs That Showcase the Beauty of Lab-Grown Diamonds
Lab-grown diamonds, created in laboratories and scientifically identical to natural diamonds, are gaining attention both domestically and internationally for their reduced environmental impact and accessible pricing.
BRILLIANCE+ has previously offered many engagement rings featuring lab-grown diamonds as the main centerpiece. Now, the brand introduces new designs that combine the charm of lab-grown diamonds with the traditional eternity style, a symbol of eternal love.
Three Rings Featuring Fancy Shape Diamonds
The brand has created three eternity designs featuring fancy shape lab-grown diamonds arranged in continuous patterns.
*Note: While the round brilliant cut is the most famous diamond cutting style when viewed from above, diamonds polished into other shapes are called "fancy shapes."
'Folia' PT950 Platinum
'Folia' K18YG Yellow Gold
'Folia' is an eternity ring featuring marquise-cut diamonds arranged to resemble laurel leaves, a symbol of eternity. The three-dimensional design evokes the breath of life, bringing modernity and dignified elegance to the finger. Minimal prongs allow full appreciation of the graceful expression of the marquise cut.
'Refina' PT950 Platinum
'Refina' K18YG Yellow Gold
'Refina' is an eternity ring featuring both marquise-cut and round-cut diamonds arranged to resemble laurel leaves, a symbol of eternity. The wreath-like design brings charm and radiance to the finger. The reverse side features a lace-inspired pattern, offering beauty even in the hidden details.
'Eleniqu' PT950 Platinum
'Eleniqu' K18YG Yellow Gold
'Eleniqu' is an eternity ring featuring emerald-cut diamonds in a continuous arrangement. The sleek prongs allow full appreciation of the emerald cut's deep, transparent expression.
Bracelet That Expands Coordination Possibilities
'Dima' PT950 Platinum / 2.1mm width
'Dima' K18YG Yellow Gold / 2.5mm width
The luxurious tennis bracelet 'Dima' is worn like a ring of light. Its minimal, modern aesthetic enhances the beauty of diamonds, and the design features a secure stopper mechanism, making it suitable for various occasions.
Available in two widths and three lengths, offering plenty of sizing options to achieve the perfect fit.
Elegant Sophistication and Brilliance Unique to Lab-Grown Diamonds
A key element in creating beautiful eternity designs is consistency in the size and shape of each stone.
However, finding multiple natural diamonds with similar balance is not easy. This becomes even more challenging when using fancy shape diamonds (which don't have strict cutting ratios) or larger, rarer high-carat diamonds.
The refined elegance of perfectly matched stone sizes and shapes, achieved with large, brilliant diamonds, is a unique advantage of lab-grown diamond eternity designs.
In addition to these new pieces, BRILLIANCE+ accepts custom engagement ring orders featuring lab-grown diamonds in their showrooms. Customers can select their own centerpiece diamond, allowing each person to enjoy brilliance that matches their values through diverse styles.
